'NITED STATES PATENT FFICE.

CHRISTIAN BARRY, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVED Al R-TIGHT CAN.

Specification forming part of Letters Patent No. 81,24 3, dated August18, 1868.

To all whom fit 'may concern Be it known that I, GHRIsrIAN BARRY, ofPhiladelphia, in the county of Philadelphia and State `of Pennsylvania,have invented a new and useful Improvement in Air-Tight Cans; and I dohereby declare that the following Vis a full, clear, and exactdescription thereof, which will enable othersskilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure lis averticallongitudinal section of my improved can, and showing a set of tools forforming the seam which fastens on the top or cover of the can.

In the manufacture of air-tight cans, as heretofore practiced, it hasbeen foundimpossible to attach the top or cover by a seam withoutleaving a hole through said cover for the introduction of a tool forforming the seam.

This hole afterward had to be closed by soldering on a piece or plate ofthe metal of which the can was made.

The object of my invention is to furnish a can made by fastening on thecover with a seam, the tools being applied outside of the can; andconsists in forming the can with a depressed or struck-up cover, so thatthe tools for forming and closing the same can be applied outside of thecan, as hereinafter more fully described.

The bottom A of the can may be 'formed and attached with Va seam, in theordinary way, l

struck up into a dish form, as represented in the drawings, so that thesides of said struckup cover may lie against the sides C of the can,allowing the tool for forming the seam to be inserted into thedepression of the top or cover in the same way that it would be insertedinto the can to form theseam which fastens on the bottom A.

The seam which fastens on the cover may be closed down by a tool similarto the one represented in Fig. l or it may be formed by the same toolthat forms the bottom seam; or a tool may be used working in a verticalposition, for convenience in fastening on the tops or covers in fullcans.

What I claim as new, and desire to secure by Letters Patent, is-

A cylindrical can having ends flaring from the direct line of the body,and the lid or cover for the top or bottom of which is swaged ordepressed and bent at the edge, so as to overlap the flaring end of thecan to which it is secured, substantially in the manner herein describedand represented.

CHRISTIAN BARRY.
